ZITYMens Golf Shirt Short Sleeve Sport Moisture Wicking Performance Print Golf Polo Shirts for Men Collared Casual T-Shirt

I don't understand the size guide? is this another country's size guide? i am in usa and the man i am ordering for is usually a xxl.

The sizing description is a bit tough for me. I have the chest of a large, but the waste of a medium - can anyone offer insight to their experience?

How long is the tail . Normal or extra long

sleeves look too short?
